About 4A0234Z
4A0234Z is the ICD-10-PCS code for a measurement procedure on the cardiac using a percutaneous approach with electrical activity. In ICD-10-PCS, measurement means determining the level of a physiological or physical function at a point in time.
In plain terms, this corresponds to other cardiovascular stress test, the ICD-9-CM procedure title it maps to (89.44).
For a different body part, codes include 4A0034Z (central nervous) and 4A0134Z (peripheral nervous).
The same procedure with a different approach is coded 4A0204Z (open), 4A0274Z (via natural or artificial opening), 4A0284Z (via natural or artificial opening endoscopic) and 4A02X4Z (external).
With a different device, use 4A0239Z (output), 4A023CZ (rate), 4A023FZ (rhythm), 4A023HZ (sound) and 4A023PZ (action currents).
It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
